“Why should a pilot have to leave the cockpit in the first place??? That’s just asking for trouble, on so many levels. And if there isn’t a small toilet in the cockpit, there should be.”
There isn’t a toilet in the Cockpit, certainly not on that plane, and I don’t know that any do have one.
I'm no aeronautical engineer, but that seems like a security oversight.
All a terrorist would have to do then is wait for a pilot to open the door and head for the toilet. Then the terrorist could rush the cockpit before the door is closed again. It would seem to me that he'd have a real shot of getting into the cockpit. Then all hell breaks loose.
